Abstract

With the demand for total hip arthroplasty continuing it is essential that the longest follow-up cases remain under continuous review.

Fifty one of the primary Charnley low-frictional torques arthroplasties have passed 30 years follow-up: mean 31 years (30–36): 42 are women and 9 men. Their mean age at surgery was 47 years (24–64). At the latest follow-up two have had a late deep infection, three a dislocation, nine a radiologically loose cup, two a loose stem and one had had a fracture of the shaft of the femur, and one a fractured stem, with only the fractured stem coming to revision.

Clinical results remain satisfactory. Wear and loosening of the cup remains the long term problem. Further improvement and even longer follow-up and successful results of the Charnley LFA will come from materials which offer the greatest resistance to wear.
